8 Claims. (Cl. Gli-190) This invention relates to knit, fabrics havingelastic threads incorporated therein and more particularly to knitfabrics of the type described suitable for use as hosiery tops andit isan Object of 'this inventionto provide a rib fabric for use as a hosiery.top` whichvhas a continuous elastic thread incorporated thereinintermittently, preferably in 'portions only ofv successive courses. 1-In the drawing, the figure is a substantially diagrammatic view showingthe relations of the fabric loops and the Aincorporated elastic yarn' ina fabric "in accordance with this invention,

the view showing theA loops of portions of two 5 rib tops knitcontinuously. l

In the drawing the fabric portion is shown as 4it cornes from themachine, the courses at the bottom of the sheet being the first knit.The

gure is broken as all courses shown are not 9" consecutive and portionsof some of the wales are, in the drawing, oiset from the Positions inwhich they actually occur in the fabric. The

courses shown, beginning at the bottom, are the courses shortly beforethe press-olf of one 'rib top and rthe courses then continue through thepress-off of that rib top, the start-up of the succeeding rib top andinto the body portion. 'The rib top shown is a rib top such as is madeby the usual hosiery top ribber and is shown for the 3" purpose ofillustration only, as it is to be understood the invention is equallyapplicable to rib fabric knit on other ftypesf' of rib knittingmachines.

The rib tops illustrated areshown as knit in afcontinuous string of asingley continuous main l or body yarn A, the needles being operated to,

form the make-up or starting course I of atop in' the revolution in4which the cylinder needles- .are operated to cast oilI theirv loops inthe pressofi course at the completion of a knit top. As shown, the dialneedles retain their loops during the press-o so successive rib tops arejoined, p together by the loops of the wales knit by the `dial needles.Following the start-up course I there is knit a course 2 of rib fabricand a course I knit 'on the cylinder needles only, the dial needlestaking yarn but not casting of the previously drawn loops. Followingcourse I are"4 two courses and 5 knit on the cylinder needles only, thedial needles being inactive butretaining the loops previously taken.During the knitting of courses I and I the elastic thread Ris laid inback of the cylinder needles and below the dial needles so vaste beheldbetween the cylinder and dial needle wales of the fabric forapproximately 11/2 to 1% courses and thenrwithdrawn, the holder for theelastic thread being rotated where the needle cylinder is stationary soas to lay in the elastic thread continuously in advance f of theknitting point. Two courses-s and 1 of 5 rib fabric are then knit. theelastic thread being laid in between cylinder and dial needle wales fora part of each course and being thenwithdrawn for the remainder of thatcourse or revolution of the knitting cams" the elastic yarn 10 `holderremaining stationary each time at -the needle at which the elasticthread is Withdrawn until the KVelastic threadguide is again operated toposition the elastic thread for laying-in in the next or a succeedingcourse or revolution when the elastic thread holder is again advanced.Following course 1, a course 8 is then 4knit on the cylinder needlesonly, thel dial needles taking yarnr butI retaining the loops previouslytaken. The elastic thread guide is operated to lay vin 20 the elasticthread for a portion of a revolutionv during the knitting of course 8and also during the knitting `of the following courses 9 and i0 knit onthecylinder needles only, the dial needles being inactive but retainingthe loops previously 25 taken. Courses il, I2, i3 etc., of rib fabricare then knit, the number of courses being suilicient `to provide a ribtopof the desired length and the elastic thread is incorporated in thefabric for the desired portion of each of the desired'30 courses.

Inthe drawing the elastic thread is shown nas incorporated for'a protionof each of a number of the rib fabric coursesof a top, as from course Ilto course 80, but it is to be understood. the `35 elastic thread'needJnot be incorporated in all courses but may be incorporatedlin recurringcourses of any desired spacing.' It is also to be understood that thenumber of needle wales for which the elastic thread is incorporated ineach 40 course, as shown in the figure, is purely an'arbitrary selectionand that the extent for which the elastic thread is incorporated inl acourse n may be varied; thus as shown in lcourses lll to 42 and Nto 58the elastic thread is incorpo- 45 rated for but one-half the extentto`which it is incorporated in courses Il to 24. AChanging the extent towhich the elastic thread is incorpo; rated in a course variesthe amountof elastic thread in the 'fabric land the tension exerted 5 thereby whenstretched. Thus, in courses-,II to 24 the -elastic thread may beincorporated for a fourth or a. nfth of each course and the elas- .ticthread at any one needle Wale is inevery fourth or fifth course, whilein courses I0 to 5I 55 where it is incorporated for an eighth ora tenthof a course the elastic thread, at any one Wale, is in every eighth ortenth course and the elastic thread incorporated in that Aportion of atop is but a half of what is incorporated in the courses Il to 24.

When the elastic thread has been incorporated for a suicient numberofcourses it is withdrawn, as in course 80, and keptfrom the needlesuntil it is again presented to the needles at the beginning of the nexttop knit, the elastic thread being allowed to oat from where it waswithdrawn in the knitting of one top to where it is inserted in theknitting of the succeeding top.

In the top illustrated several courses of rib fabric, as courses 8l to83, are knit after the with drawal of the elastic thread, then there areknit a loose course 84, several`rib fabric courses; as 85 to 88, acourse 89 in which the cylinder needles knit and the dial needles .takeyarn and retain the loops previously drawn, two courses Sil and 9i inwhich the cylinder needles knit :and the dial needles are inactive butretain the loops previously taken and rib fabric courses 92 and 93.

' The cylinder needles are then operated to press off the loops ofcourse 93 and during the same revolution of the cam ring both thecylinder and dial needles are operated to take yarn and the dial needlesto cast off the loops of course 93,-

thus placing on all theneedlesthe loops for the starting course l. y

I claim:

1. Seamless tubular knit fabric comprising a plurality of courses and acontinuous elastic thread incorporated unknit for a portion only of eachof a plurality of courses, said portions extending progressively aroundthe entire fabric.

2. Seamless tubular knit vfabric comprising a plurality of courses and acontinuous elastic thread incorporated unknit in said fabric instaggered portions only of a plurality of courses, said staggeredportions being oiset progressively around the fabric.

3. Circular knit. rib fabric comprising a plu- I rality of successivecourses of loops ofv a yarn and a continuous elastic thread incorporatedunknit for portions only of successive courses, said portions extending'progressively around said fabric.

4. Circular'knit rib fabric comprising aplurality of courses and acontinuous elastic thread incorporated unknit for a portion only of eachj of a plurality of courses, said elastic thread being incorporated to adifferent extent in dilerent courses and said portions being oisetprogressively around said fabric.

5. Circular knit fabric comprising a plurality of courses and acontinuous elastic thread incorporated unknit in staggered portions onlyof a plurality of courses, said portions being progressively offsetaround said fabric.

6. Circular knit fabric comprising a plurality ofcourses and acontinuous elastic thread incorporated unknit in` portions only of eachof a plurality of courses, said portions extending/progressively aroundsaid fabric.

7. Circular knit fabric comprising a plurality of courses and acontinuous elastic thread in` corporated unknit in portions only of eachof a plurality of courses, said portions extending progressively aroundthe fabric.

8. Circular knit fabric comprising a plurality of courses and acontinuous elastic thread incorporatedunknit in portions only of each ofa plurality of courses, successive incorporated portions of said elasticthread engaging offset groups of needle wales entirely around saidfabric.
